I'm inclined to say yes, but I don't know much about that particular PSU. However, 600W should be plenty enough for a 560Ti. But to be sure you can always talk to Phaedrus, he seems to be one of the PSU gurus here.
Just noticed that that PSU only has 1x 6+2 pin PCI-e connector and the GTX 560Ti uses 2x 6 pin. You could technically use a molex to PCI-e adapter, but that is hardly ideal and I personally wouldn't recommended doing that. I'd say judging by what others are saying about the amps being low and the lack of 2x 6 pin connectors, that PSU won't work.
